intended for automated processors that don't want to send messages to senders without verified domains (because the address may be forged, and the processor doesn't want to bother innocent bystanders). such delivery attempts will fail with a permanent error immediately, typically resulting in a DSN message to the original sender. the configurable error message will normally be included in the DSN, so it could have alternative instructions.
